Webhook notifications aren't working right now

I have a webhook application where I manage the start / end events and join / left events of the participants in a webinar. The notifications arrived correctly until yesterday, but now the join / left notifications are not fired (while the start / end ones continue to work). No changes have been made to the configuration and application in the meantime.
There are no errors detected, the notifications are simply not fired and are not even present in the Call Logs in the dashboard.

No error detected, but notification non fired.

Which App Type (OAuth / Chatbot / JWT / Webhook)?

Which Endpoint/s?

How To Reproduce (If applicable)
Steps to reproduce the behavior:

  1. Request URL / Headers (without credentials) / Body
  2. See error

Screenshots (If applicable)

Additional context

Update: While a few hours ago the join and left notifications did not arrive at all now they are fired with a huge and unusual delay varying between 20 and 40 minutes, while previously the delay was limited to a few seconds.

Hey @mustentdev,

Thanks for reporting this.

Can you private message me the delayed webhook payloads and meetingIDs so i can check the logs?


Hi, thanks for you reply.

First of all I would like to tell you that yesterday I did not encounter any particular problems (3-4 seconds delay).

Below I give you an example which I copied from the log to the dashboard.

Meeting id: ***********
Event: webinar.participant_joined
Event date (in my local time) 19/4/2020 10:48:32
Notify fired (in my local time) 19/4/2020 11:20.21 (more than half an hour later)

Also this is the code of a meeting for which the join / left notifications never came: ***********

Thanks @mustentdev,

Please let us know if you see additional webhook issues.


At this moment there are no issues, the notifications arrive with an acceptable delay of 3-4 seconds.

thanks, Daniele
